Preporing the TTL Pentq Prism
Employ the TTL Pentq Prism (45) os fqr os
possible only with o flexible eyepiece cup.
Spectocle-weorers use o vision-correction
lens (see the instruction monuol for the
co mero).
After plocing the TTL Pento Prism in the
comero turn the shutter-speedsetting disc
(51) once f rom stop to stop so thqt the
driver pin (44) will engoge the grooves on
the boitom side of the-fft Pento Prism (45).
This hos been done correctly if, when the
shutter-speedsetting disc (51) is turned, the
shutter-speed setting knob (10) is tu rn ing,
too.
Ploce the mercury oxide element (Mollory
PX 13) in the chomber below the lid @71:
plus sign outwords.
